Abstract
Applying materials on the precut surface in ductile metal cuttings can greatly improve the machinability, due to a reduction in friction between the lamella of the chip. We define this effect as the lubricant applying effect (called as LAE hereafter). This paper dealt with the influence of the LAE on the cutting of difficult-to-cut material the Ni-base superalloy Inconel 718. The experimental results demonstrate that the LAE played an important role in lubrication of the Inconel 718 cutting.
